Paper Abstract

With the development of electrophysiology in this century, many predictions made by visual psychophysics, like trichromacy, have been linked to data on visual cells, but the proposed links with respect to chromatic and achromatic visual processes are not clearly consistent beyond photoabsorption, and the interactions of photoreceptor signals at the higher visual stages are still under very active study and discussion. This paper reviews the problems involved in trying to relate an important postulate of psychophysical zone theories of color vision--the post-receptor chromatic-achromatic independence to neurophysiological data and visual multiplexing.
